Failed to save target content: Index and length must refer to a location within the string. Parameter name: length.

Hello,

I get the message in object when I try to save the file as a pptx.

I have tried 'saving target as' without the target text, creating a new project / individual file, changing the location where I save files, but the problem persists. The only similar issue I found a post on was with an MIF file, 

Based on the answer provided there, I am trying to remove each slide, import the source in Studio each time, saving target as, to see if I can spot the (hopefully) one slide that is causing the issue.

Since the presentation is long and full of charts (and who knows if what I am doing will be useful anyway?) are there any other suggestions in the meantime?

Thank you all in advance for your help!

Cheers,

Stefania
